specification of Letters Patent.

Patented Oct. 30, '1917.

To all whom z' may concern Be it known that I,PHIL1r A. MYERS, a citizen of the United States, residing at Ashland, in the county` of Ashland and State of Ohio,` have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawing.v x f This invention relates to pumps. The object of the present invention is to provide a construction which will require very little attention and in which friction and resistance are reduced to a minimum. To achieve this object it is my intention to arrange the working head with reference to the pump so that resistance and frictional engagement between the relatively moving parts are reduced to a minimum; to` reduce the number of relatively moving parts asfar as possible and to provide a suitable system of lubrication for' such relatively moving parts as are nec/essary to the proper operation of the mechanism.

In the accompa ing drawings, Figure 1 is an elevation ill strating one embodiment ofthe invention/in which the cross headis driven byl means of an a similar elevation looking toward the right of Fig. 1; Fig. 3, is an elevation illustrating a slightly modified form iii-'which a crank is used for operating and reciprocating the crosshead; and Fig. 4 Ais a detail view of one of the iside arms showing a'spring attached thereto which serves to balance the' pump` and even up the momentum.

The mechanism herein illustrated shows the working head arranged for well work beyond the'limit of suction. The working head also has a straight stroke adaptable for either single or double acting cylinders as may be required. The mechanism herein shown, however, is for the'purpose of illustration only. c

Referring to Figs. 1 and 24, l indicates the discharge head of the pump provided with a suitable orifice 2, a packing gland 3 and a reciprocating piston rod 4. The pump is provided with a suitable ledge or .support 5 for supporting the working head 6 which comprises the mechanism for reciprocating the piston rod. The working head is adjustable u on "the ledge 5 and is provided with suita le legs 7 and feet 8 resting upon the said ledge. This adjustabilityt allows eccentric; Fig. 2 is the working head Ato be located in proper position with reference to the pump so that friction and wear. Supported by the' legs 7 is a sectional casing comprising a lower section 9 `adapted to receive oil 0r other lubricating substance and an upper section 10 comprising the cylindrical upper portion 11 and attached -to the lower section, as indicated at 12. The assembled casing has journal'ed therein a gear13 which is driven by means of the pinion 14 also located within the casing. The pinion and gear are rotated from any suitable vsource of power through the pulley 15. Attached tothe gear 13 is an eccentric 16 provided with an arm 17 Iattached to the slide 18 forming a part of the cross head. This slide reciprocates within the-cylindrical portion of the upper section of the casing and the whole working head is so mounted 'with reference to the pump that this slide is substantially in alinement with the piston rod ,and reciprocates back and forth in thepsame'directionitherewith and in alinement therewith. By the above arrangement the resistance and friction is practically eliminated because contact between the points is avoided. Fixed to the slide is the transversely extending member 19 ofthe cross head which reciprocates within the slots 2O arranged on opposite sides of the cylindrical sectional portion of the casing. Atveach side of the casing is a side arm 21. These'arms are connecte 'at their lower ends to a cross/piece 22 fixed at 23 to the piston rod and at their upper ends to the member 19. The side arms 21 reciprocate in a vertical line only and have no radial movement around\ axes. -It is, therefore, unnecessary to lubricate these parts to .reduce the friction.

'In order to lubricatel the slide 18 and asl sociated parts, such as the' eccentric arm, etc., I have provided a suitable pump 24 which -serves to pump `oil from the lower section of the casing through a conduit 25 to a point above the slide, whereby these parts are properly lubricated. This pump may also be utilized, if desired, tb ,feed oil to a point above the shaft supporting the gear wheel 13.'. Any suitable device may be used for-actuating the pump and any suitable pump may be used. In the present instance I have shown an Veccentric 26 conever, is such that there will be very little rubbing between Athe relatively Amovable parts.l

The specific means for transferring the power from the transmission devices within the casing to the slide may be varied. In Figs. 1 and 2 for the purposes of illustration I haveshown an eccentric and arm` connected thereto. In Fig. 3 I have illustrated a form in which a crank 27 connected by a connecting rod 28 'to the slide is' utilized for transferring this power from the gear 13 to the slide.

In Fig. 4 I have illustrated a detail which may be easily applied to the side arms illustrated in the construction shown in Figs. l, 2 and 3. Referring to Fig. @the side arm may be indicated by 'the numeral 29. This arm reciprocates through yan apertured abutment 3,0 and is provided at the upper portion thereof with an adjustable collar 31. Interposed between the abutment which is attached 'to any suitable part of the fixed frame and the adjustable collar is a compression spring 32., A spring of a similar nature is applied to the arms at each side. Thefunction iof the above device is to balance the pump and even np the momentum thereof.

While I have shown and ,describedI one embodiment of the invention it will be understood that the same has been 'chosen Yfor the'purposes of illustration only, and that I do not desire to be limited to the details of construction shown and described.

Having thus fully described my invention, what` I claim as new and desire to` secure by Letters Patent, is :-V-

l. In a pump, the combination, with a discharge head and a piston rod passing through said head, and guided thereby, of a lbase plate supporting said head, a frame comprising legs carried by said plate, said frame having integral therewith a semicylindrical casingftransmission devices comprising actuating gearing journaled in said casing, a second semi-cylindrical casing above and fast to 'the first casing, said sec- Lacasse by kept rigidly in line with said piston rod,-

means outside said `casing for connecting said piston rod to said cross'head, an oil pump in the lower part of said irst casing, and a pipe leading from said pump to a point above said cross head, and thus lubrieating said cross head and said transmission gearing by the gravity of the oil.

2. In a pump, the combination, with a piston rod, and a plate servingv to guide the same, of agear casing, semi-cylindrical in shape, having an imperforate bottom with legs integral therewith and fast to said plate, said casing serving to hold a supply of lubricating oil, transmission gearing mounted in said casing, a second casing, also semicylindrical in shape, closely fitting said first casing and having a vertically .extending cylindrical portion, a cross head mounted in said cylindrical portion, and connected to both said transmission gearing and said piston rod, and an oilpurup in said irst casing, having connections to pump oil from the oil supply in said casing, and to elevate said oil and to discharge it in said cylindrical portion above said cross head, thus lubrieating said cross head and gearing by the gravity of the oil.

3. In a pump, the combination, with a gear casing having an imperforate bottom serving to retain an oil supply, transmission gearing mounted in said casing, a cross head` mounted in said casing directly over and driven by said gearing, a pump piston rod directly under said casing and having connections to said cross head outside said casing, and an oil pump in said casing having connections to-elevate oil from said supply and to discharge it in said casing above said cross head, thus lubricating said' cross head and gearing bythe gravity of the oil.

i."In a pump, the combination, with a casing having an imperforate bottom serving `to'retain an oil supply, transmission gearing in said casing, a cross head mounted in said casing dlrectly over and having conf nections to said transmission gearing, and

an oil pump mounted in said casing and having connections to elevate'oil from said oil supply and to discharge it inthe upper part of said casing labove said cross head,

thus lubricating said cross head and said gearing by the gravity of the oil.

In testimony whereof, I aiix mv si ature.
